EDWARD A. FIELD, or SIDNEY, MAIN-E. Letters Patent No. 72,006, dated December 10, 1867.

IMPROVEMENT IN HORSB-RAKES.

TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, EDWARD A. FIELD, of Sidney, in the county of Kcnnebec, and State of Maine, have invented an Improved Horse-Rake; and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a longitudinal section, and

Figure 2 a rear elevation of a horse-rake provided with my invention.

In such drawings, A denotes the axle, having two wheels, B B, and provided with thills, G C, in the ordinary way. To the upper side or part of the axle, a series of arms, D D, &c., is applied, so that each one of such arms may be capable of turning vertically on 5. rod, a, going through it near its inner end, and supported by standards, 6 6, extending up from the axle. Each of such arms also turns independently of the others to a certain extent, viz, so far as it may be allowed to by a rope, c, which runs along underneath allthe arms, and is fastened to the outer two of the series,or to their braces, the said rope being arranged in the triangular space between each arm, its brace 01, and tooth E. The rope, while allowing the arms to conform to the surface of the ground, prevents them, or any one or more of them, from being thrown up too high by any obstacle against which the tooth or teeth of the arms may be drawn into contact while the rake may be in use. The arrangement of the rope causes it to be protected from the grass, which, were it not for the braces, might catch and accumulate upon it. There is a tooth, E, to each of the arms D, the tooth being fixed in the arm by means of I acylindrical shank or tenon, e,iprojecting from the upperend', and at an obtuse angle with the axis of the tooth.

A long staple or wire,f, embraces the tooth, and extends from it into and through and is fastened to the arm,

each wire being arranged in manner as represented. It serves to draw the tooth up against the brace d, whose ends are simply inserted loosely in sockets made in the arm and tooth. There is a clamp-screw, h, to each arm,

it being screwed into the arm and against the side of the tenon, and for the purpose of fastening the tooth in position in the arm. The object of the arrangement of the tenon at an obtuse angle with the axis of its .tooth is to enable such tooth to be readily adjusted to a proper position with respect to that tooth or those teeth next adjacent to it.

It is frequently the case that the teeth, while in use, become bent or warped, and in consequence thereof they are thrown more or less into abnormal positions. It is to enable them to be readily restored to their normal positions that I arrange the tenon of each at an obtuse angle with the axis of the tooth, the same admitting of the tooth being turned a little so as to restore it to place when it may be out of a correct position. The brace to each tooth will readily move with it, and allow it to be moved as circumstances may require.

I do not-claim a horse-rake made with a series of arms applied to an axle provided with thills and wheels,

each of such arms having a tooth extending from it, and being hinged to the axle; nor do I claim the mere combination and arrangement of a brace, d, with the tooth E and its arm D; nor do I claim the application of a rope to the several teeth, so that such rope, while extending from one to the other of them, may be gapable of being slipped up or down on them, the same being as represented in the United States Patent, No. 21.712: but

What I claim as my invention or improvement is as follows:

I. I claim the application of each tooth, E, to its arm D by means of a round tenon arranged at an obtuse angle with the axis of the tooth, and going into the arm, the. same being substantially as and for the purpose described.

2. I also claim the combination as well as the arrangement of the adjustable brace 01 and the staple or claspingwire f, with the arm and the tooth, when applied by means substantially as specified, viz, a cylindrical tenon arranged at an obtuse angle with the axis of the tooth, and going into a corresponding hole made in the arm.

3. I also claim the combination of the clamping-screw It with the arm, and the tooth applied to such arm by a tenon arranged at an obtuse angle-with the axis of the tooth, as specified.

4. I also claim the arrangement of the rope, or its equivalent, with the several arms and their teeth, and

the braces thereof, the said rope being to operate as and for the purpose specified.

EDWARD A. FIELD.
